n; all whom it may concern:

Be it known that 1, JAMES Joanna Mn)- nn cnnooit, a SHbJQCt. of the Kingof Great 7 Britain, residing at Sault Ste. Marie, county of Chippewa,and State of Michigan, have i invented 'certail'i new and useful Improve.ments in Motor-Vehicles, of which the following is a specification.

My invention relates to motor vehicles.

the. provision of a motor vehicle, particularly adapted for operation bya gasolene engine,

having novel traction wheels and gearing,j whereby v the machine maybereadily an ranged for plowing or for moving from place to place; noveldriving means adapted .for rt-wersing. and other iiistrumentalities,

all as fully set forth hereinafter in the appended claims.

In the accompanying drawings: Figure 1 is a plan view of my lIUPIOVQdmotor vehicle; Fig. '2. a side elevation showing the same in ope 'ativcconnection with a gasolene engine; Fig.- 3, a similar View from theop-)osite side offthc machine showing the ad ustablc traction wheel in itselevated position.

vThe frame 1 of the machine is preferably of metal to afford rigidityand strength, and at its front it is provided with a steering wheel 2carried in a woke l) which is pro- \ided with a stem 4 jonrnaled in asliding frame 5 which works in guides 6 in frame 1. Connected to thestem 4: above the crosspiece of frame 5 and thus -supporting thesteering wheel, is a head 7 which is operated by steering mechanism 8. Arocker 9, which is journaled in suitable hearings on frame 1 andoperated by a lever 10, has articulated connections 11 with the lowerpart of frame 5, whereby the steering wheel may be raised and loweredand held at any desired position, thus regulating the depth of thefurrow when the machine is used as a motor plow.

The rear part of the machine is carried hy a shaft 12 mounted independing brackets on frame 1 to which a traction wheel 13 is secured. Ashaft 14. is carried by dcpcnding brackets on the frame 1 on whichloosely mounted a wheel carrier '15 in which is journaled a shaft 16 towhich the other traction wheel 17, is secured. Shaft it) carries acollar 113 on its inner end to retain said shaft against displacement.Keyed to the shaft 13 a gear 18 which meshes with an idler gear 19 onshaft 14, the idler and recited l l '1 l l l l gear meshing with a gear20 keyed. to shaft 1. Connected to a rocker 21. which is ournaled inframe 1, is a lever 22 which is attached to the wheel carrier by a linkA horizontally movable catch A on frame 1 is adapted to be swung overthe lever 22 and to hold its free end down upon a cross-liar 25, when itis desired, for the traction wheels 13 and 17 to propel the machinewhile it is The present invention has for its objects 1 "wardly and theside of the frame 1 drops correspondingly until the shaft 16 strikesagainst the outer shaft supporting bracket of frame 1, the relativearrangement of the parts being then as shown in Fig. 3.

A yoke at the front of frame 1 and a guide 27 at the rear thereof arefor the reception of a tongue or pole of any implement, such as aharrow, for instance, which it may be desired to (law by the machine,and thus the machine is rendered adaptable as a tractor for any piece offarm machinery.

'A coupling 28 at the rear of frame 1 is used for attaching the machineto the implement which'is to be drawn.

The gasolene tank is shown atit) and the gasolcne engine at 30, thelatter being geared to a gear 31 secured to ashaft on which are loosely'splined large and small gears 33 and 34; which are adapted to. meshwith either a small gear 85 or a. large gear o6 fast on a shaft 37 whichcarries a sprocket wheel 38 connected by chain 39 to a sprocketwheel 40fast on shaft 1 A gear shifter 41 operated by a lever +12 is employedfor shifting the gears 33 and on the shaft- By causing gear 33 to enga egear the machine may be propelled faster, as when it is desired to moveit from place to place without carnying on a plowing or other similaroperation, but when the gear 34: is in mesh with the large gear '36, thenecessary relatively slow travel of the machine is obtained connectingrod 48 to a lever 49'. Normally and 61 may be used to adjust the plow.
